Description
Technical Field
[0001] This utility model relates to the field of heating furnace technology, and in particular to a heating furnace for uniform heating control mechanism for forgings. Background Technology
[0002] Heating furnaces are a type of equipment widely used in industrial production. They are mainly used to heat workpieces to the required temperature to meet the needs of processes such as rolling, forging, and heat treatment.
[0003] A heating furnace uses the high-temperature flame and flue gas generated by the combustion of fuel inside the furnace as a heat source to heat the forgings. The fuel is first sprayed out from the burner and burned. The high-temperature flame transfers heat to the forgings in the furnace through radiation. The high-temperature flue gas transfers heat to the furnace tubes or forgings in the convection chamber through convection, so that the forgings gradually heat up to the required temperature.
[0004] During the heating process of forgings in a heating furnace, it is found that when a large amount of hot gas flows inside the furnace, the hot gas will escape from the inlet and outlet, causing heat loss. The lost hot gas will take away a lot of heat, which can easily lead to uneven temperature distribution inside the heating furnace.
[0005] Therefore, this utility model provides a uniform heating control mechanism for forgings in a heating furnace. Utility Model Content
[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a uniform heating control mechanism for forgings in a heating furnace.
[0007] To achieve the above objectives, the technical solution of this utility model is to design a uniform heating control mechanism for forgings in a heating furnace, including a heating furnace body. The heating furnace body has a first heating zone, a second heating zone, and a third heating zone inside. A conveyor belt is installed in the middle of the heating furnace body. A circulation assembly is installed on the top of the heating furnace body. A filter assembly is installed in the middle of the circulation assembly. Guide assemblies are installed at both ends of the heating furnace body. The circulation assembly includes two heat flow boxes, which are fixedly connected to the ends of the heating furnace body and arranged opposite each other. An exhaust pipe is fixedly connected to the top of each heat flow box, and a fan is fixedly connected to the end of the exhaust pipe. The fan is installed on the top of the heating furnace body. An exhaust pipe is fixedly connected to the middle of the blower, and the end of the exhaust pipe is fixedly connected to the top of the heating furnace body. A protective component is provided on the outside of the blower. Through the above structure, precise temperature control can be achieved. Each heating zone can be set with different heating temperatures and times according to the material, size and heating requirements of the forging. The circulation component can continuously circulate the hot air inside the heating furnace body. This circulating heating method can make the forging more evenly heated, reduce the phenomenon of local overheating or underheating of the forging inside the heating furnace body, and improve the overall heating efficiency. The even heating of the forging during the heating process can effectively reduce the thermal stress and deformation problems caused by uneven temperature, thereby accelerating the heat transfer and uniformity.
[0008] Preferably, the filtration assembly includes a first filter plate fixedly connected inside the heat flow chamber, and a second filter plate fixedly connected in the middle of the heat flow chamber. The second filter plate has a lower density than the first filter plate. The first and second filter plates are disposed on the side close to the heating furnace body. Through the above structure, the two filter plates with different densities can effectively filter out impurities and particulate matter in the hot air flow, reducing the entry of these impurities into the equipment. This makes the filtered hot air flow purer, effectively reducing the pollution of the internal environment of the heating furnace body by impurities and particulate matter, reducing the obstruction of heat transfer, and thus improving heating efficiency.
[0009] Preferably, the guiding assembly includes two sets of slide rails, each set of slide rails being fixed to the end of the heating furnace body. The two sets of slide rails are arranged opposite to each other. A slider is slidably connected to the middle of the slide rail, and a slide rod is fixedly connected to the side wall of the slider. The slide rod passes through the end of the slide rail, and a spring is fixedly connected to the side wall of the slider and the end of the slide rail. The spring is fixedly connected to the outside of the slide rod. A support rod is fixedly connected to the top of the slider, and a roller is rotatably connected to the middle of the support rod. With the above structure, the forging can be placed in the center position inside the heating furnace body. The center of the heating furnace body is usually the area with the highest and most uniform temperature distribution, which effectively makes the forging more evenly heated inside the heating furnace body and can effectively reduce the time and cost of adjustment caused by deviations in the forging during the transmission process.
[0010] Preferably, the protective assembly includes two protective boxes, which are fixed to the top of the heating furnace body and to the outside of the corresponding fan. The exhaust pipe and the vent pipe penetrate the side wall of the protective box. A through slot is provided on the top of the protective box, and a fan is installed in the middle of the through slot. The above structure can block impurities and dust from the external environment from entering the fan, effectively reducing the wear or blockage of the internal mechanical structure of the fan caused by dust and impurities. It also reduces the damage to the fan caused by impact from external objects. Furthermore, the fan can increase the airflow inside the protective box during the operation of the fan, effectively dissipating heat from the fan during use.
[0011] Preferably, a filter screen is fixed to the top of the protective box and fixed to the corresponding through slot. The above structure can effectively block external dust and particles from adhering to the fan surface, reduce the wear or blockage of the fan blades caused by these impurities, keep the fan clean and unobstructed, and reduce the decrease in air volume and increase in energy consumption caused by dust accumulation.
[0012] Preferably, two insulation plates are fixed to the side wall of the heating furnace body, and the two insulation plates are arranged opposite each other. The above structure reduces the heat loss inside the heating furnace body, effectively improves the thermal efficiency inside the furnace, and can achieve and maintain the required heating temperature with lower energy consumption, thereby reducing production costs and heat loss.
[0013] The advantages and beneficial effects of this utility model are as follows: 1. The uniform heating control mechanism for forgings in the heating furnace described in this utility model can achieve precise temperature control through the above structure. Each heating zone can be set with different heating temperatures and times according to the material, size and heating requirements of the forging. The circulation component can continuously circulate the hot air flow inside the heating furnace body. This circulating heating method can make the forging more uniformly heated and reduce the phenomenon of local overheating or underheating of the forging inside the heating furnace body.
[0014] 2. The uniform heating control mechanism for forgings in a heating furnace described in this utility model can effectively filter out impurities and particulate matter in the hot airflow through the first and second filter plates of different densities, reducing the amount of these impurities entering the equipment. This makes the filtered hot airflow purer, effectively reducing the pollution of the internal environment of the heating furnace body by impurities and particulate matter, reducing the obstruction of heat transfer, and thus improving heating efficiency.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0018] like Figures 1 to 4As shown in the figure, a uniform heating control mechanism for forgings in a heating furnace according to an embodiment of the present invention includes a heating furnace body 1. The heating furnace body 1 has a first heating zone 10, a second heating zone 11, and a third heating zone 12 inside. A conveyor belt 13 is installed in the middle of the heating furnace body 1. A circulation assembly 2 is installed on the top of the heating furnace body 1. A filter assembly 3 is installed in the middle of the circulation assembly 2. Guide assemblies 4 are installed at both ends of the heating furnace body 1. The circulation assembly 2 includes two heat flow boxes 21, which are fixed to the ends of the heating furnace body 1 and are arranged opposite to each other. A ventilation duct 22 is fixedly connected to the top of the furnace body 1, and a fan 23 is fixedly connected to the end of the ventilation duct 22. The fan 23 is installed on the top of the furnace body 1, and an exhaust duct 24 is fixedly connected to the middle of the fan 23. The end of the exhaust duct 24 is fixedly connected to the top of the furnace body 1. A protective component 5 is provided outside the fan 23. The forging is first conveyed by the conveyor belt 13 and guided by the guide component 4 into the furnace body 1. The first heating zone 10, the second heating zone 11, and the third heating zone 12 are independently controlled according to the real-time temperature of the forging, so that multiple independent heating areas are realized inside the furnace body 1. During the heating process inside the furnace body 1, the hot airflow inside the furnace body 1 is filtered by the filter assembly 3 and then circulates inside the furnace body 1 through the circulation assembly 2, ensuring uniform heating of the forgings after they enter the furnace body 1. As the forgings enter the furnace body 1, the hot airflow inside the furnace body 1 is discharged from both ends. At this time, the blower 23 is energized and turned on, drawing the hot airflow that is about to be discharged into the heat flow box 21. After the hot airflow is concentrated inside the heat flow box 21, it enters the exhaust pipe 22 and is then discharged back into the furnace body 1 by the blower 23. The above structure enables precise temperature control. Each heating zone can be set with different heating temperatures and times according to the material, size, and heating requirements of the forging. The circulation component 2 continuously circulates the hot air inside the furnace body 1. This circulating heating method makes the forging more evenly heated, reduces local overheating or underheating of the forging inside the furnace body 1, and improves the overall heating efficiency. The even heating of the forging during the heating process can effectively reduce thermal stress and deformation caused by uneven temperature, thereby accelerating heat transfer and uniformity.
[0019] like Figures 2 to 3As shown, the filter assembly 3 includes a first filter plate 31, which is fixed inside the heat flow box 21. A second filter plate 32 is fixed in the middle of the heat flow box 21. The second filter plate 32 has a lower density than the first filter plate 31. The first filter plate 31 and the second filter plate 32 are located on the side close to the heating furnace body 1. During operation, when the hot airflow inside the heating furnace body 1 enters the heat flow box 21, it first passes through the first filter plate 31 to pre-treat the hot airflow, intercepting large particles inside the hot airflow. As the airflow continues to flow, the hot airflow passes through the second filter plate 32 to intercept small particles. Through the above structure, the first filter plate 31 and the second filter plate 32 with different densities can effectively filter out impurities and particulate matter in the hot airflow, reducing the amount of these impurities entering the equipment. This makes the filtered hot airflow purer, effectively reducing the pollution of the internal environment of the heating furnace body 1 by impurities and particulate matter, reducing the obstruction of heat transfer, and thus improving heating efficiency.
[0020] like Figures 1 to 4 As shown, the guide assembly 4 includes two sets of slide rails 41, each set of slide rails 41 being fixed to the end of the heating furnace body 1. The two sets of slide rails 41 are arranged opposite to each other. A slider 42 is slidably connected to the middle of the slide rail 41. A slide rod 43 is fixedly connected to the side wall of the slider 42, and the slide rod 43 passes through the end of the slide rail 41. A spring 44 is fixedly connected to the side wall of the slider 42 and the end of the slide rail 41. The spring 44 is fixedly connected to the outside of the slide rod 43. A support rod 45 is fixedly connected to the top of the slider 42. A roller 46 is rotatably connected to the middle of the support rod 45. During operation, when the forging is conveyed into the heating furnace body 1 in the middle of the conveyor belt 13, it contacts the forging through the two rollers 46. As the forging continues to move, the rollers 46 move with the forging. The support rod 45 rotates in the middle. When the forging is large, it applies pressure to the roller 46. At this time, the support rod 45, which is under pressure, slides inside the slide rail 41 through the slider 42. At the same time, it pushes the slide rod 43 to slide to one side at the end of the slide rail 41. The spring 44 generates elastic contraction to adapt to forgings of different sizes. The two rollers 46 guide the forging. The above structure can place the forging in the center of the heating furnace body 1. The center of the heating furnace body 1 is usually the area with the highest temperature and the most uniform distribution. This effectively makes the forging heat more evenly inside the heating furnace body 1 and can effectively reduce the time and cost of adjustment caused by deviations in the forging during the transmission process.
[0021] like Figures 1 to 3As shown, the protective component 5 includes two protective boxes 51, which are fixed to the top of the heating furnace body 1 and to the outside of the corresponding fan 23. The exhaust pipe 22 and the vent pipe 24 pass through the side wall of the protective box 51. A through groove 52 is opened on the top of the protective box 51, and a fan 53 is installed in the middle of the through groove 52. During operation, when the fan 23 is running, it is protected by the protective box 51 to prevent external objects from directly contacting the fan 23. At the same time, the fan 53 is turned on and rotates at high speed. The fan 53 dissipates the heat generated by the fan 23 from the inside of the protective box 51 to the external environment. The above structure can prevent impurities and dust in the external environment from entering the fan 23, effectively reducing the wear or blockage of the internal mechanical structure of the fan 23 caused by dust and impurities. It also reduces the damage to the fan 23 caused by the impact of external objects. In addition, the fan 53 can increase the airflow inside the protective box 51 during the operation of the fan 23, effectively dissipating heat from the fan 23 during use.
[0022] like Figures 1 to 3 As shown, a filter 6 is fixedly attached to the top of the protective box 51. The filter 6 is fixedly attached to the corresponding through slot 52. During operation, when the fan 53 is in use, the filter 6 intercepts dust and impurities in the outside air. The above structure can effectively prevent external dust and particles from adhering to the surface of the fan 53, reducing the wear or blockage of the blades in the fan 53 caused by these impurities. It can keep the fan 53 clean and unobstructed, and reduce the decrease in airflow and increase in energy consumption caused by dust accumulation.
[0023] like Figure 1 As shown, two insulation plates 7 are fixed to the side wall of the heating furnace body 1. The two insulation plates 7 are arranged opposite each other. During operation, when the forging is heated, the insulation plates 7 isolate the two sides of the heating furnace body 1 from the external environment. The above structure reduces the heat loss inside the heating furnace body 1, effectively improves the thermal efficiency inside the furnace, and can achieve and maintain the required heating temperature with lower energy consumption, thereby reducing production costs and heat loss.
[0024] During operation, the forgings are first conveyed by conveyor belt 13 and guided by guide assembly 4 into the heating furnace body 1. The first heating zone 10, second heating zone 11, and third heating zone 12 are independently controlled according to the real-time temperature of the forgings, creating multiple independently heated areas within the heating furnace body 1. Simultaneously, during heating within the furnace body 1, the hot airflow inside the furnace body 1 is filtered by filter assembly 3 and circulates within the furnace body 1, ensuring uniform heating of the forgings upon entry. As the forgings enter the furnace body 1, the hot airflow is discharged from both ends. At this time, the blower 23 is energized and turned on, drawing the discharged hot airflow into the heat flow box 21. The hot airflow is concentrated in the heat flow box 21 and then enters the exhaust pipe 22, where it is again discharged into the heating furnace body 1 by the blower 23. When the hot airflow enters the heat flow box 21, it first passes through the first filter plate 31 for pretreatment, intercepting large particles within the hot airflow. The hot airflow continues to flow, and the second filter plate 32 intercepts small particles. When the forging is conveyed into the heating furnace body 1 in the middle of the conveyor belt 13, it comes into contact with the forging through two rollers 46. As the forging continues to move, the rollers 46 rotate with the forging in the middle of the support rod 45. When the forging is large, it applies pressure to the rollers 46. At this time, the support rod 45, which is under pressure, slides inside the slide rail 41 through the slider 42, and at the same time pushes the slide rod 43 to slide to one side at the end of the slide rail 41. The spring 44 generates elastic contraction to adapt to forgings of different sizes. The forging is guided by two rollers 46. When the fan 23 is running, it is protected by the protective box 51 to prevent external objects from directly contacting the fan 23. At the same time, the fan 53 is turned on and rotates at high speed. The fan 53 exhausts the heat generated by the fan 23 from the inside of the protective box 51 to the external environment. During the use of the fan 53, the filter screen 6 intercepts dust and impurities in the external air. During the heating of the forging, the insulation plate 7 isolates the two sides of the heating furnace body 1 from the external environment.
[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
